APEX Listener

We are planing to use APEX with APEX listener in production site for better security .
Under this circumstances, do we still need to install XMLDB .
If it is, could you please let me know what functionality of XMLDB is required when we are not in EPG mode.

Hi there,
If you do not have XDB installed, then the APEX component will be invalid. Essentially, it is an unsupported installation. If you ever need to call Oracle Support, the first thing they'll ask you to do is make the component valid (by installing XDB).
XDB is used in a number of places in APEX - as an XMLTYPE in collections, parsing of Web Service results, XML data loading and unloading, XLIFF translation file parsing, probably a few more areas that I'm not recalling now.
I hope this helps.

APEX LISTENER Install troubleshooting

Hi, I need help.. :-)
Default Database connection not configured properly
What I have done:
     ALTER USER APEX_LISTENER ACCOUNT UNLOCK;
     ALTER USER APEX_PUBLIC_USER ACCOUNT UNLOCK;
     ALTER USER APEX_REST_PUBLIC_USER ACCOUNT UNLOCK;
     connect APEX_LISTENER/mypasswd1
     connect APEX_PUBLIC_USER/mypasswd2
     connect APEX_REST_PUBLIC_USER/mypasswd1
Check default.xml
password: replaced encrypted one with clear text one for APEX_PUBLIC_USER to ensure it is correct
even tried APEX_LISTENER password just incase
Is there a simple JDBC test to see if it connects? it is APEX_PUBLIC_USER who is connecting isn't it?

That could be a problem.
I was answering the question:
BillC wrote:

You can use SQLPLUS to make sure you have the correct password.
After that, it is the SERVER, PORT, SID/SERVICE in the APEX listener you need to confirm.
You can TNSPING to confirm you have the correct selections for those.
You can always re-run the java -jar apex.war setup command to all of the basic settings.
The reason I mention that is because if you modify the settings manually - we need to ask "which file?" because there is the default and the database specific one too.
Try making a request to the service in standalone mode and you should get a terminal output (the window stays open) with a more detailed error. I would guess there will be an ORA-12514, TNS listener does not currently know of service requested in descriptor or something similar that will give you the "debug" information you are looking for.

APEX Listener with APEX 3.0 on 11gR2

Yes, I am crazy.
We have many many APEX applications in APEX 3.0 running on a 10.2.0.4 database that needs desperately to be upgraded. As a test, I've set up a clean 11gR2 database and copied the production APEX database into it via datapump. I set up APEX Listener, as I don't have any OAS sitting around and the EPG doesn't seem to be supported for APEX 3.0... the Listener doesn't say one way or the other.
When trying to log in, I get the login page, but it tries to reference files such as apex_get_3_1.js while I only have files such as htmldb_get.js in my images directory in production. I noticed it is looking for what appears to be 3.1 files instead of 3.0 files... which concerns me.
The APEX listener appears to be more than just a Java PL/SQL gateway.
Is there a minimum version of APEX the APEX Listener supports?
Interested in pointers!
Rob

Hi Rob,
Yes, I am crazy.Why would that be? ;)
We have many many APEX applications in APEX 3.0 running on a 10.2.0.4 database that needs desperately to be upgraded. As a test, I've set up a clean 11gR2 database and copied the production APEX database into it via datapump. I set up APEX Listener, as I don't have any OAS sitting around and the EPG doesn't seem to be supported for APEX 3.0... the Listener doesn't say one way or the other.APEX 3.0 is supprted by EPG. See the [url http://docs.oracle.com/cd/B32472_01/doc/install.300/b32468/post_inst.htm#CHDBEJDA]APEX 3.0 Installation Guide for details.
APEX Listener is capable of hosting APEX 3.0 as well, though APEX 3.0 wasn't supported anymore when APEX Listener was initially released. The current APEX release at that time was 4.0, so this would be the first version to be known as really stable, whereas you won't get any support for older releases anymore. From personal experience I know that there are now issues with APEX 3.1 and APEX Listener, so it'll probably also work with 3.0.
Concerning your database release, the minimum for APEX Listener is 10.2.0.3, so you're definetly safe on that part, though I'd recommend to upgrade as regular support for 10.2 databases ended.
When trying to log in, I get the login page, but it tries to reference files such as apex_get_3_1.js while I only have files such as htmldb_get.js in my images directory in production. I noticed it is looking for what appears to be 3.1 files instead of 3.0 files... which concerns me.This indicates that your APEX would actually be a 3.1 and you should update you images directory.
The APEX listener appears to be more than just a Java PL/SQL gateway.It is, but this has nothing to do with your 3.1 JS files, if this is why you stated this.
Is there a minimum version of APEX the APEX Listener supports?As mentioned above, 4.0 would be a safe approach, but 3.1 will definetly work, 3.0 probably will as well. I'd recommend you find out which APEX version is actually installed on your database before you consider any upgrade operations. Run the following query as privileged user:
SELECT comp_name, version, status
FROM dba_registry
WHERE comp_id = 'APEX';-Udo

Apex Listener vs. Oracle Application Server... advantages?

Are there advantages to installing Apex Listener over using an existing Oracle Application Server instance to serve Apex applications?
We have an existing application server instance in production. Would introducing Apex Listener and the extra overhead be of any advantage?
Thanks in advance for your thoughts.

Hello "Portal Dude",
Are there advantages to installing Apex Listener over using an existing Oracle Application Server instance to serve Apex applications?APEX Listener introduces some additional features, such as Resource Templates, but lacks some others. Some people might want to migrate from OAS to another JEE Container that doesn't come along with a OHS/mod_plsql. Depending on the JEE Container, you could use AJP for load balancing, avoiding plain HTTP through a firewall, etc.
Would introducing Apex Listener and the extra overhead be of any advantage?The "extra overhead" may be smaller than you think. If you don't need the HTTP_Server component any longer, but can just deploy APEX Listener on the OC4J of your OAS, you might even save some bytes.
For several other aspects, there have been a few posts on that topic in the past:
{thread:id=1100122}
{thread:id=1555908}
{thread:id=1594158}
If there's anything you don't find in either the posts or the documentation, don't hesitate to ask.

APEX listener - empty page ??

Hi,
I have installed tomcat / APEX listener on Oracle Enterprise Linux 5 (with 11gR2 database)
The configuration seems to be done ... but the page: http://oel52server:8080/apex/apex give me an empty page ?
do you know what's wrong ?
Cyryl

Thanks for the answers.
I have a similar problem-- but I believe it may not be because of JDK ver. (becaue I already use ver. 6.0).
Although I am able to see the Apex login page. http://localhost:8888/apex/, but no images are displayed. Moreover it asks for Workspace, Username, Password which I am unaware of (it did not ask for any such information while installing apex). It looks like none of the buttons/links are active. Did I do anything wrong while installing apex?
This is how I installed Apex.
1. Downloaded and installed tomcat application server and Apex Listener as per the instructions given in the link:
http://www.oracle.com/technology/products/database/application_express/html/apex_listener_install_web.html
(section B. Installing with Apache Tomcat in the installation )
2. The images are copied to the following location (as given in the instruction):
C:\apache-tomcat-6.0.24\webapps\ROOT\images
3. Started both oracle db server and tomcat app. server
4. Opened the page http://localhost:8888/apex/Config
at this point I get the login page with no images and inactive links/buttons.
Appreciate any help.
Thank you,
Pravy

Apex Listener commercial license

Hello,
I created applications with Apex and I'm about to install Apex on an other database.
I 'll maybe choose Apex Listener but I don't know if there is a commercial license for it: would my customers have to pay to use an apex application that runs with Apex Listener ??
Thanks.
Fanny

If you use the ORACLE HTTP server (Apache with modplsql), it's free with the database license.
If you use the APEX Listener, you need an App Server. The App Server requires a License.
For APEX, it's licensed with the Database for all version , Standard One, Standard, Enterprise, Express.

APEX Listener with Free environment

Hi,
I was going through APEX Listener Installation guide and found that the supported installations are
*1) with WebLogic*
*2) Glassfish &*
*3) OC4J*
All of the above are associated with licensing cost. Is there any free installation scenario? As 11gXE is free to store upto 11GB of user data, I was thinking to install it with Glassfish for my small application which is not expected to have 11GB of user data over the next 4-5 years. Today I had a chat with one of the local Oracle Sales guy and I found that licensing cost is huge for Glassfish.
I don't know whether standalone APEX Listener will serve the purpose of having my application available over the internet. Please forgive me; I am a novice in the field of networking.
Could you please provide me the details of the free or low cost alternatives of the above scenarios? One option I know is to go for hosting services for low cost. But to me that is also huge.
Any kind of help is appreciated.
Thanks,

Supported in this context is supported by Oracle in that you can open an SR with support.oracle.com or not.
ApexListener runs on most J2EE Containers. Free ones include GlassFish Community Server and Tomcat. ApexListener runs on GF as well as Tomcat, but you cannot run to Oracle Support if you have an issue. You have to seek help here, on this forum, if you cannot resolve things yourself :(

APEX Listener versus classic Application Server

Currently we use the APEX Listener with the stand-alone configuration to access the URL af an APEX application.
This might not be a suitable situation for a production environment.
In a short, here are the (possible) requirements:
- Sessions must be able to access at the same time the same APEX application and page.
Let's say 500 users should be able to access it with no trouble.
- If there are some pages accessed very frequently, they should be cached (how?) without having to request them all the time from the database.
- If more than 500 users are accessing the application, to avoid latency, there should be a "mechanism" to make them "waiting" until the allowed amount of concurrent sessions is below 500, and without impacting (or with low impact) of other working sessions.
I have little knowledge of middle ware environment, but this seems to me specifications for an application server and or a web server.
Hera are my questions:
1) Is it possible to implement such above mechanism with the APEX Listener?
2) If not possible, what should I consider?
Thanks by advance for sharing your experience.
Kind Regards.

Essentially you are asking how do I tune the number of database connections and also how do I tune the number of HTTP request handling threads.
The former is controlled via the Listener configuration files, specifying the size of the connection pool etc, if you look at the configuration file or use the SQL Developer Listener admin tool the settings are pretty self explanatory, the latter is controlled by the application server, see below for WebLogic documentation on this:

Any idea ???

Hello,
sorry for the late reply.
I have installed Apex Listener.1.0.2.238.15.24 on Oracle Containers for J2EE 10g standalone (10.1.3.1.1) That's a pretty old version of OC4J, and a pretty old one of APEX Listener, too. Is there any reason for not choosing a more recent release?
Despite that, your OC4J might also be using an unsupported (and outdated) Java version. APEX Listener needs at least a JDK 1.6 Update 20.
Please check whether your OC4J is using an appropriate JDK.

APEX LIstener administration via SQLDeveloper 3.2.2 error

Hi,
I configured the APEX Listener 2 on my server and everything works fine.
I also configured the Restful webservices that also works fine in APEX.
Now , I would like to be able to configure the APEX Listener via SQLDeveloper 3.2.2
I changed the defaults.xml file to allow a non HTTPS connection and configured the adminlistener password.
When I try to connect to the APEX Listener via SQLDeveloper to retrieve the configuration, I get the following error :
Error occured retrieving Administration Settings from Listener.
Unexpected Content-Type:application/json; charset=UTF-8
APEX Listener is installed on Windows (french version).
Thanks
Francis.

Hi Francis, I'm getting the same error.
(I do note however that SQLDev does make the connection - and even though I get the UTF8 error, I can upload/download config files. This would appear to be a warning/info message. But still annoying.)
I am using CentOS 5.8 Linux, Glassfish 3.1.2, SQLDev 3.2.20.09, ApEx 4.2. DB is 11.2.0.3, AL32UTF8. So this problem is not unique to Windows or French.

APEX Listener EA2 Standalone CLOB error

I'm testing the APEX Listener EA2 release in Standalone mode on CentOS against Oracle XE.
My RESTful service calls use the Media Resource type to return a CLOB that I format myself inside a function:
select 'application/json', my_function_that_returns_json_in_a_clob from dual
In the EA2 release, this is generating an error if the function returns more than 4000 bytes (works with 4000, fails with 4001). It is as though the function is getting cast as a varchar2 somewhere. I verified that the function will correctly return a large result to other sources (dbms_output, for instance).
The APEX Listener Log reports the error as:
oracle.dbtools.rt.web.HttpEndpointBase restfulServices
SEVERE: ORA-22922: nonexistent LOB value
Here's a Test Case:
create or replace function test_size(p_cnt in integer) return clob
is
l_clob clob;
begin
for i in 1..p_cnt loop
l_clob:=l_clob||'a';
end loop;
return l_clob;
end;
Then create a RESTful service call:
Method: "GET"
Source Type: "Media Resource"
Source: select 'application/json', test_size(4001) from dual
Thanks,
Tim

Thanks for your thorough reply!
Unfortunately, your workaround doesn't fix the problem with EA2. It encounters the 4000 character limit as well.
I understand your advice regarding using the QUERY type. I chose the Media Resource strategy for two main reasons:
1. These services calls are for our mobile developers. Because they use some predefined frameworks for managing data that comes to the mobile app, they wanted the json to distinguish between data sets (rather than every data set being called "items"). I am able to format the json in such a way that it doesn't confuse their code. Is there another way to customize the format of the default json created by the QUERY type?
2. I need to conduct some other business as part of the call. For instance, the service passes in a user's credentials which I use to authenticate and then retrieve the appropriate results based on who they are. Currently, I have stored procedures that authenticate APEX users or LDAP users.
Perhaps old habits die hard, but I find that if I just do all of this myself in a stored function, I have all of the control I need. If you have other recommended strategies, I'm all ears.
Thanks!

Apex Listener authentication.

I want to use Apex Listener for my pl/sql web application (now I use mod_plsql).
How can I implement authentication in order to protect pages from unauthorized use (like OWA_CUSTOM does in nod_plsql)?

Hi Udo and Tullio,
I am testing the listener against APEX 4.1. I would like to integrate the APEX applications in our SSO system. We are using SAML2, so I have configured a Weblogic Server for working as a Service Provider. In this server I have deployed the apex.war and I have registered the /apex/* pattern in my Identity Provider (Active Directory Federation Services). In this way, when I make a request of any of my APEX applications (apex/f?p=123:...), if I have not a valid session I am redirected to the Identity Provider Login page. This is working fine, more or less, I have to do more testing...
My question is, do you think that is this the best approach for securing the APEX applications? In order to everything works ok, I have to declare a security constraint in the web.xml...
<security-constraint>
     <web-resource-collection>
          <web-resource-name>APEX Application Calls</web-resource-name>
          <url-pattern>/*</url-pattern>
          <http-method>GET</http-method>
          <http-method>POST</http-method>
     </web-resource-collection>
     <auth-constraint>
          <role-name>FederatedUsers</role-name>
     </auth-constraint>
</security-constraint>
...and in the weblogic.xml I just map the FederatedUsers against a principal:
<security-role-assignment>
     <role-name>FederatedUsers</role-name>
     <principal-name>users</principal-name>
</security-role-assignment>
Also I have declared a filter for injecting some info in the headers request (needed for the APEX applications), but this is another story...
Thanks in advance,
Luis

Apex listener, POST, internal body-variable

Hello,
I am using Apex-Listener 1.1.2.131.15.23 on SUSE Linux 11.3./Oracle XE 10. I created a Resource Template with POST-methode and the following pl/sql-block:
declare
l_nuLen1 number;
l_nuLen2 number;
begin
l_nuLen1 := length(:body);
l_nuLen2 := dbms_lob.getLength(:body);
:status := triple.coxSmsAt.fSetResponse(:contentType || '(' || to_char(length(:contentType)) || ')',to_char(l_nuLen1) || '/' || to_char(l_nuLen2),:body);
end;
In my STF on the database there is no problem to get the value of :contentType. But if I want to access to the :body-variable most of the tries ended in a server-error. With the PL/SQL-block above there is no server-error but the result is l_nuLen1 = 5, l_nuLen2 = 0 and no value apears in the fSetResponse-StoredFunction for :body.
Can someone help me?
Thanks
Martin

Well the idea behind APEX (Application Express ) is that you can develop mostly declarativly. This is what a RAD tool/framework should do. You seem to think that your requirements somehow force you to send your own constructed code to the listener. Why? Apex in general is very good at hiding this logic from you. Maybe instead of asking a deeply technical question, start by explaining what you want to achieve (business language not technical explaination!). Then lets talk how to use Apex in a normal way to achieve the same result. This might even help you to develop better stuff in faster time.

Your requirement would violate several standard design principles. One should not do so without good reasoning.

Apex Listener in standalone mode, how to set/reset db connection.

Sometime ago I installed Apex Listener for testing, then I removed it.
Now I downloaded last version, installed it in standalone mode and try to set the DB connection.
However when I try to edit in listenerAdmin page the db connection parameters I can't : they are greyed and report the connection informations I gave in my first test installation.
How can I change them ?
How can I avoid all fields in listenerAdmin greyed ?
Tks

Hello Tullio,
you can run /listenerConfigure/ only as long as there is no configuration available. The database parameters can only be setup when the APEX Listener is not connected due to the state of its connection pool. Once it is established, you can only configure it offline by editing the apex-config.xml . That's why the parameters are greyed out in /listenerAdmin/.
You probably only removed the war file of your test installation, but not the apex.home including the apex-config.xml that is stored in there. So your new installation found the old home and reused the connection.
You could either edit the apex-config.xml or delete the apex.home and rerun /listenerConfigure/
If you run on a windows system, you'll find the apex.home in your users TEMP, usually located in the temp folder underneath the local settings of your user profile. The directory to locate is now called "apex".
